Question

Which among the following specifies the correct sequence of steps followed to obtain primitive sequence in speech?

(a) Isolate the basic sequence, analyse the basic sequence, analyse the primitive sequence

(b) Isolate the basic sequence, isolate the primitive sequence, analyse the basic sequence

(c) Analyse the basic sequence, isolate the basic sequence, analyse the primitive sequence

(d) Isolate the basic sequence, analyse the primitive sequence, analyse the basic sequence

The question was asked at a job interview.

My doubt is from Architecture in chapter Cognitive Radio Architecture of Cognitive Radio

Answer 1

The correct answer is (a) Isolate the basic sequence, analyse the basic sequence, analyse the primitive sequence

For explanation I would say: In speech, the sensor obtains input that correlate with the definition of basic sequence. In order to obtain the primitive sequence, the basic sequence is isolated from background noise. The basic sequence is analysed to identify potential boundaries of primitive sequence. The primitive sequence is then extracted and statistically analysed.
